Disable Caps Lock Key in Linux

I hate the caps lock key. So, in my ~/.bashrc I have the following line to disable caps lock:
xmodmap -e "remove lock = Caps_Lock"

To turn off caps lock key, enter:
$ xmodmap -e "remove lock = Caps_Lock"
Now caps key is disabled. To enable caps key, enter:
$ xmodmap -e "add lock = Caps_Lock"
